Comment (by anonymous):

 seq_first_rest_n.patch fixes BOOST_PP_SEQ_FIRST_N and BOOST_PP_SEQ_REST_N,
 so they both accept sequences of length 256 now. As a bonus feature, for
 preprocessors sufficiantly handling empty arguments (or those expanding to
 nothing), both macros process empty sequences as well. Usage of empty
 sequences is outside of the specs of the preprocessor code, and is not
 generally supported by the preprocessor library.

 The previous patches did not handle empty sequences properly for DMC based
 preprocessors. This is corrected here, no other difference is introduced.

 This patch supersedes all previous ones.
